What you get every Thursday

Regulatory tracker

Every filing deadline, decoded before your legal team gets to it

CSRD, SEC climate disclosure, ISSB, and state-level reporting rules, translated into what changes for your next filing — not a summary of the statute.

Greenwashing watchdog

We trace the claim back to the data, so you don't have to

Weekly teardown of a public sustainability claim — offset registry, supply chain audit, or emissions filing — showing exactly where it holds up and where it doesn't.

Carbon accounting tactics

The Scope 3 methodology your auditor will actually accept

Practical accounting approaches from teams who've passed assurance — supplier-specific factors, allocation methods, and the documentation that survives review.

I stopped reading three other ESG newsletters after two months of this one. It's the only one that reads like it was written by someone who has actually sat in a materiality assessment.

The greenwashing teardowns are now required reading for our comms team before anything sustainability-related goes external. It's changed how we write claims.

California’s SB 253 enforcement window opens — three gaps in Scope 3 filings

8:02 AM

Morning — forty early SB 253 filings crossed our desk this month, and the pattern is already clear: assurance providers are rejecting supplier-specific Scope 3 data almost twice as often as last year’s CSRD dry run.

“The filings that pass review treat supplier data like financial data — versioned, sourced, and reconciled.”

  • Which three data fields assurance providers flag most
  • The reconciliation step most Scope 3 programs skip
  • A template disclosure paragraph that passed review twice

Full breakdown below.

Questions, answered

Sustainability officers, ESG analysts, and corporate strategy leads who need to translate regulation into board-ready decisions — not marketing teams looking for green talking points.

Each regulatory update is rewritten as a one-page operational brief: what changed, your effective deadline, and the three things your compliance team should do this quarter.

We trace specific claims back to underlying data — offset registries, supply chain audits, emissions filings — and show our work, so you can defend or challenge a claim in your own reporting.

Yes. We don't accept sponsorship from carbon credit brokers, ESG software vendors, or reporting platforms. When we recommend a tool or methodology, it's because we tested it.

Every Thursday morning, five minutes to read. We assume you have fifteen other things demanding your attention — the issue is built to survive being read in a hallway.

Sustainability leadership starts with the Thursday inbox.
